The House: 6 Week update
Whew, what a week! I am wiped out! Firstly, all week we've continued working in our little mini-groups, labeled the 'A' team and 'B' team. We're in the 'A' team. We really like it. Everyone gets along very well. Now, I'll just go straight through the houses... that'll be easier. yeah.
House 1, 2, AND 3: roof framing done (trusses and sheathing all installed, but no shingles)
House 4 ('A' team): Exterior walls finished, Interior framing finished, garage framing finished, OSB sheathing all placed, house squared and braced, and all the little details that have to be done to get the house ready for roof trusses. Roof trusses have been delivered, but are not installed.
House 5 (on the 'B' team): rimboard, floor trusses, load bearing wall, subfloor, and a few exterior walls are done.
House 6-Ours! (A team): Started tonight! yaaaay! I'll go into lots of detail below.
House 7, 8, & 9: no changes from last week.
Now, our house.
The first thing we do is measure in 6" from every single corner. Then we use a long chalk line to draw a straight edge for us to line up the floor with. This ensures all our walls will be square. You can't measure from the foundation, because the concrete isn't necessarily straight.
After the chalk line is down, we use that to measure from. We use treated wood everywhere that will touch concrete. So first we have to measure them carefully and cut out holes in the green board where the massive concrete bolts come out of the foundation. Then, we lay down a long roll of insulation, that looks like this:
Then, we place the green board that we pre-measured, cut, and drilled. It goes on top of the insulation. Using metal plates, washers, and nuts, we bolt the green board to the foundation.
After that, the inside of the green board gets caulked, and the outside gets the rimboard. Rim board also must be carefully measured and have notches cut out where it goes over the bolts and metal plates. It's heavy too!
Meanwhile, down in the basement, other people are working hard to build the load bearing basement wall. It must be framed according to the floorplan. We again use treated wood on the bottom, but regular 2x4s for the studs and top plates. We use a long string to make sure it is square. When at last the wall is framed, we all help lift it into place.
(Yes, we really did move THAT fast! j/k)
And that's about where we left off tonight. Saturday: floor joists!
But before I sign off, I wanted to send out a very special THANK YOU to all of our many, many volunteers that have helped us this week, and in previous weeks as well. It has already been so fun and so special to have you come help us, and to show you our new home. I hope you've enjoyed it too! It is a huge undertaking and we couldn't do this without you!
